TWO-OUNCE CAMERA TAKES EIGHT PHOTOS (Aug, 1933)

That’s actually very impressive. I wonder how well it worked.

TWO-OUNCE CAMERA TAKES EIGHT PHOTOS
A pygmy camera, hardly larger than a golf ball, has been put upon the market in New York City. It weighs less than two ounces, and carries sufficient sixteen-millimeter film, the size used in amateur moving picture cameras, to take eight exposures. The camera’s size can be noted in the picture above.

16mm film, shot movie style (sprockets on the sides of the image) uses only 7.5mm of film per frame, so 8 shots means 60mm (less than 2.5″) of film. Shooting like a 35mm camera (sprocket on top an bottom, a 10.25mm height means about 13.7mm, or 110mm per 8 frames – call it 4.5″ of film.

I’d go with the smaller size, and a black-bag loader with a built in cutter. That would be easier to deal with than the Minox’s oddball film (but then again that was loaded into cartridges.)
